Prototype pollution vulnerability in swiper

[GabrielJesusS]

Hello,

First of all, thank you for the recent release and for addressing the prototype pollution vulnerability.

I noticed that version 12.1.2 includes a fix for this issue. However, the affected code appears to exist in several previous versions as well. Some of my projects depend on older major versions of Swiper, and upgrading to the latest major version is not currently feasible.

Do you plan to backport this fix to previous major versions?

If not, would you accept a pull request targeting those versions with a minimal patch for this vulnerability? I would be willing to contribute if that aligns with the project’s maintenance policy.

Thank you for your time.
